Add or Change Node Attributes

Evaluates expressions against the node table, with the same centrality and structural vocabulary that select_nodes() offers, and stores the results as node columns.

Usage

mutate_nodes(x, ..., keep_format = FALSE, directed = NULL)

Arguments

x

Network input.

...

Named expressions, for example hub = degree > 3 or score = pagerank * 100. Available names are the existing node columns plus every measure and predicate listed under select_nodes.

keep_format

Logical. Return the input format when TRUE. Note that only igraph and cograph_network formats can carry node attributes; a matrix cannot, and the new columns are lost.

directed

Logical or NULL. If NULL (default), auto-detect.

Value

A cograph_network whose node table has the new columns, or the input format when keep_format = TRUE.
